[Oral health and precariousness in pregnant women].

Objective: Systematic full-mouth dental examination during pregnancy is an official preventive measure recently advocated by the French Health policy. The aim of this study was firstly to evaluate the oral health related to some sociodemographic factors among pregnant women, and secondly to propose this dental examination together with the routine antenatal interview.

Material and method: This cross-sectional study combined several medical questionnaires with an oral examination. It concerned all pregnant women attending their routine antenatal interview in the maternity unit of the Montpellier hospital. Socioeconomic status was assessed by Epices index. So that two groups were determined : the deprived group (D), and the non-deprived group (ND).

Results: Oral examination revealed that 93% of the women were suffering from at least one oral disease, 74% had a periodontal disease (9% had a periodontitis), and 74% had at least one carious tooth. The mean Epices score was 30.5 and the mean number of carious teeth was significantly higher in the group D (3.4) than in the group ND (2.35), (p=0.02). The prevalence of periodontal disease or periodontitis were not significantly different between the two groups (p=0.81 and p=0.99 respectively). After stratification on the degree of dental hygiene knowledge, it was found that knowing about an adequate dental hygiene and specific preventive measures regarding pregnancy could reduce the gap between the oral health status of the two socioeconomic groups.

Conclusion: This study showed that performing an oral examination, at the same time than the antenatal interview, could highly improve the knowledge about dental hygiene among pregnant women and the screening of oral diseases, especially for deprived population.
